Question

I was reading Threading from within a class with static and non-static methods and I am in a similar situation.

I have a static method that pulls data from a resource and creates some runtime objects based on the data.

static class Worker{
    public static MyObject DoWork(string filename){
        MyObject mo = new MyObject();

        // ... does some work

        return mo;
    }
}

The method takes awhile (in this case it is reading 5-10mb files) and returns an object.

I want to take this method and use it in a multiple thread situation so I can read multiple files at once. Design issues / guidelines aside, how would multiple threads access this code?

Let’s say I have something like this…

class ThreadedWorker {
    public void Run() {
        Thread t = new Thread(OnRun);
        t.Start();
    }

    void OnRun() {
        MyObject mo = Worker.DoWork("somefilename");

        mo.WriteToConsole();
    }
}

Does the static method run for each thread, allowing for parallel execution?

Answer 1

Yes, the method should be able to run fine in multiple threads. The only thing you should worry about is accessing the same file in multiple threads at the same time.
